Concrete Post-Tensioning Anchor Assembly for Corrosion-Free Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current post-tensioning systems face challenges with corrosion and inefficient anchor securing methods, particularly due to the use of nails which can compromise the integrity of the connection and expose anchors to corrosive elements, and existing methods are prone to misalignment and contamination risks.
Innovation Solution
A post-tensioning system that includes an anchor member, a pocket-former member, and a bolt member with coupling mechanisms such as threads or a flange, which securely engage with each other and the form board without nails, forming a sealed and corrosion-resistant connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If nails are used to secure the anchor to the form board, then the anchor can be attached to the form, but the connection integrity is compromised and corrosion risk increases
Solution Approach 1:
The patent removes nails from the system entirely, extracting the harmful fastening method and replacing it with a nail-less attachment mechanism where the pocket-former member is secured to the form board through alternative means that do not compromise the anchor connection or expose metal to corrosion
Solution Approach 2:
The pocket-former member serves as an intermediary component between the anchor and the form board, providing a sealed connection that eliminates the need for nails while maintaining structural integrity and preventing corrosion of the anchor assembly
2Ease of manufacture
If traditional anchor securing methods are used, then the anchor can be attached to the form, but misalignment and contamination risks increase
Solution Approach 1:
The pocket-former member is pre-configured with alignment features and attachment mechanisms that guide proper positioning of the anchor relative to the form board before concrete pouring, eliminating misalignment issues that occur with traditional post-installation nail securing methods
Solution Approach 2:
The pocket-former member acts as a precision intermediary component that ensures accurate alignment between the anchor and form board through its designed geometry and attachment features, preventing contamination and misalignment risks associated with traditional methods
3Productivity
If the anchor is exposed to corrosive elements, then the post-tensioning system can function, but corrosion resistance decreases
Solution Approach 1:
The patent employs a polymer encapsulation shell around the anchor and a sealed pocket-former member that acts as a protective film, creating a barrier that prevents corrosive elements from reaching the metal components while maintaining full system functionality
Solution Approach 2:
The sealed pocket-former member serves as a protective intermediary barrier between the anchor assembly and the corrosive concrete environment, eliminating direct exposure to harmful elements while allowing the post-tensioning system to function normally
